A fining guide for vegan fining Super F!

Optimising Super-F

We recently made our rapid-action, vegan fining Super F available to purchase without an optimisation by our laboratory! However, we still strongly recommend you carefully optimise before use! So, we thought it advantageous that we go through the basics of a successful Super F optimisation.

First of all, the materials you require to optimise are as follows:

3L measuring jug

500ml measuring jug

Pipette with 0.1 ml graduations

5 x 500ml glass bottles

Refrigerator set to 4°C

Microscope kit and Haemocytometer

Super F Optimisation Method:

Set up the glass bottles with the specified dose rates and clearly label the bottles

Take a 2.5 L sample of beer post fermentation and perform a yeast count

Measure 500ml into each bottle and seal, invert three times to mix and refrigerate for 24 hours

Very carefully remove the beer from the fridge and set on a bench with a light source behind the samples

Select the rate which has the best clarity along with a compact sediment.

If you cannot measure haze it might be good to develop a grading system for your records e.g. A-F A=Brilliantly bright F= Very Turbid/Dull

Yeast counts for the best sample can validate that the bulk of the yeast has been removed.

The recommendation for dose rates to optimise to are as follows:

Super F Dosage(pints per barrel)

Dosage ml/HL

Trial Dose ml/500ml

When using Super F we always recommend that you optimise regularly. For the majority we’ve found the best results to be between 0-5°C and when the product is used in conjunction with optimised auxiliary finings and carrageenan use. Last but not least, your yeast count should be 1-8 millioncells/ml of viable yeast.
